What Are The Moisture-proof Design Methods For Dry-type Transformers?

Because the internal windings of single phase dry type transformer are encapsulated with epoxy resin or vacuum pressure impregnation technology, forming a robust solid insulation structure, effectively resisting moisture ingress, 500kva dry type transformer possesses moisture-proof characteristics.

The absence of an additional liquid medium between the windings and the core makes it difficult for moisture to migrate or accumulate in 30 kva dry type transformer, thus maintaining stable performance even in high humidity environments.

Air cooling eliminates the possibility of moisture being introduced by the liquid medium in the oil tank, reducing the path of moisture spread through the oil cooling system.

Open slots are typically avoided in the structural design, and the outer casing has a high degree of sealing, making it difficult for moisture to penetrate the internal insulation layer.

Through these design features, 50 kva dry type transformer exhibits significant moisture-proof performance in humid or coastal environments.
